After using it for a day, my eyes looked hydrated and felt great! However, I might have screwed up my own skin by giving myself a facial and making the skin around my eyes sore. I thought by applying this serum & eye cream afterwards, it would help soothe the skin and make it hydrated. BUT I actually woke up the next morning and my eyes were all puffy and red! I thought it might be these products, but I think it was a combination of different facial products and aggravating the skin. The next couple of days, the skin around my eyes were so dry and flaky – it actually hurt. I ended up getting some hydrocortisone cream which helped right away. Thankfully after using that, I was able to get back to using these products without my skin drying up and getting flaky.
